To allwzomit mag/concern.' B e it known that I, THOMAS C. SHEEHAN',acitizen of the United States,- residing Yat' Jersey City, county ofHudson', and State of New Jersey, have invented "a new ,and usefulImprovement in Honing-Machines,

` of which the following is a sp'ecication invention relates to amachine for honing razor blades, particularly vblades of the thinAreplaceable type -used in connection'4 with certain razors ofthe safetytype,

^ and its main object isto provide a machine for this purpose inwhic'hsuccessive blades are automatically .honed so that the cuttingedges of all will be'exactly'alike.-

-A further Objectis to provide, a machine in which blades are forwardediii a right line to and past the honing device so that therel will be'no'bending of the blades and consequent deformation of the' delicate cuteting edges aftenthe honing-'operation is com-1 to get out of order.

lith these and other objects not. specifi-v ,cally mentioned inV view,the invention con sists, in certain constructions and combinationswhich'will be hereinafter fully de scribed, and then specifically! setforth in the claims hereunto appended In'xthe accompanying drawings,whichl form va :part `of this specification andin which like-characters'ofreference indicate the same or similar parts`, Figure lis a plan viewof a device constructed in accord- .ance With the invention, Fig.`2 isaside Vmeans mayvary within wide limits.

In carrying the invention into effect,`there"j islprovided'means forforwarding a blade with one ofits edgesexposed, and, ythis While, incertain constructions, individual clamps moving intermittently orcontinuously may be used for this purpose, or holding meansSpecification-of Letters Patent. entgd Blah 17, 1914, i

jtheaperforation of a which projects above exposed position. There isprovided a stapluralityV of blades moving in-` termittently 5 as' shown,continuously moving forwarding in the best constructions and v means isemployed including a pair of belts l and 2 which coperatel to forward ablade or bladesplaced between them, into the W'hen belts are employedfor this purpose, they ,lmay -be variously mounted. In the deviceselected to illu'strate the invention, how' fever, the belts are mountedto contiifiuouslyv move,- in horizontal planes and to support andforwardblades with their upper edges p line past the hon"- so that therecan be no deformation of 'the delicate edges of the blades afterthe'honing operation is completed. To {this e'nd', the belt l isarranged to run over pulleys 3 and 4, and the belt 2 is arranged pulley3 is lixed'upon the upper end of a short shaft 7 journaled in a bearingS formed on a table 94 which is supported by-a frame 10. This frame 10is'the main frame of the machine. Upon the lower end of the shaft'? is'fixed a worm wheel 11- in mesh with a worm 12 fast on a horizontal'shaft 13 whicheis the main power shaft of the machine. This shaftcarries the usual pulley 13 by'means of which it is turned in awellknown manner. Similarly, the pulley 5 is'fiXed uponv the upper endof'a shaft 14 journaled in a bearing 15 formed on the 'table 9 beforere- .ferred to. Upon the lowerend of this shaft, is fixed a worm wheellin mesh with a' worm 17 fast on the shaft 1 3. The pulleys 4: and 6arerespectively loosely mounted on I studs 1 8 and 19 securedin-thetable 9.

When 'blades having a perforation, or perforations, therein, are tobehoned, means engaging the perforation, or perforations, is provided forpositively forwarding' the blade or blades. This means may vary withinwide -limits. As shown, the belt 1 yis provided `with a seriesofpinsQO'engaging blade 21, one edge of the belts l and 2 in an tionaryguide 22 mounted on the table 9 and extending along the front side ofthemachine and around the side ofthe pulley 4. This guide is spaced fromthe substantiallyequal to the thickness of the blades to be honed. soYthat it coperates with the belt to hold a blade on the pins 2O dur.-

It will bereadily understood that when a blade reaches the-far end l of thestationary guide, itis caught between the two belts and forwarded stillfarther'in the cooperating action of A rotating hone located in the pathof the exposed edge of a blade is provided, and this hone may varywithin wide limits. In certain constructions, l'a single `hone may beemployed.. In the ever, and as shown, a series of rotating hones isemployed, and these hones are 'alternately oppositely positioned oneither side of and so that both sides of the exposed edge of a blade mayb e honed during the forwarding operation. Each drawings 4consists in astone Wheel 24:A fixed upon one end of a short shaft j'ournaled in avtilting bearing 26. This' bearing is fpivoted at 27 to a bracket. 2S.The bracket '28 i's provided with a'ser'ies of elongated slots 29througli'which a series of clamping angle,

may vary. within wide limits.

screws pass for the purpose of clamping the bracket on the table 9before referred to.

An adjusting screw 31 of well known con-V struction is provided for thepurpose, of ad justing the bracket 28 toward'or awayI from the `belts 1and 2. A pair of adjusting screws 32, 33 are provided, which arethreaded into the tiltii'ig bearing 26 and the heads of which bearagainst the bracket 28. It.

will be readilyv understoodthat by the use of the mechanism justdescribe'd,`the hone may be' adjusted toward or away from the belts and'exposed edgeof a -bladecarried thereby, and that itmay also be adjustedby .a tilting action to vary the angle of the fase of the hone with'belts'. Upon Vthe other end of'the shaft 25 is fixed a pulley 34Cdriven by a belt 35 running the faces ofa blade in the threover and alsoover a pulley not shown on a line shaft over the machine.

Itwillbe noted that the axis of the rotat-f ing hone, -indicated by the.broken linegc, lies in aplane intersecting the exposed edge of theblade, Fig.l 3;, and also in a plane crossing the forwarding means at anobtuse necessary, and in certain constructions, other arrangements ofthe hones with lrespect lo the belts or other forwardingl devices may beemployed. j

For the purpose of holding a blade against the rotating honev during thehoning operation, there' is provided a guide lopposite and coperatingwith the hone,

.As shown,

however, this guide includes a bracket 36 secured to the table 9opposite the operating best constructions, hw'

Fig. 1. It is to be understood, how ever, that this arrangement is notabsolutely' and this guide in the path of the exposed edge of the blade,

of thehones shown in the edgeof the hone 24. Upon this bracket mounted aframe b riclret 36, and the latter outside the' saine. -The lug 39carries a stud 40 which passes through a suitable .aperture in the wallof 37 having two depending lugs 38 and 39, the former .within'the thebracket 36 and 'into-'the lug 38.. This stud .1s loosely fitted inthe'apertures of the bracket and lug 3S so that it may vslide freelytherethrough. Coiled aroundtha't part of the stud lying between the lug38 and the rear Wall of the bracket 36, is a spring 41 the function ofwhich is to'press the Vframe 3T against the exposed edgel of a bladeheld between the belts 1 and 2, and thereby hold it againstthefhoi'ie-24. -Movement of 4this frame toward thel hone islimit'ed bymeans.

of anI adjusting screw 42 of well known construct-ion.

All the hones are alike,fan d it is deemed unnecessary 'to repeat adetailed descriptionV of each of them. Such v description is, therefore,omitted' in the interest of brevity and l clearn'ess.

blades are successively placed by hand between the belt 1 and guide 22at 23, with the pins 2O engaging theperforations in the lblades.
